Puppeteering with Puppet

So I’ve been a very naughty sysadmin recently, one of the things I intended to do early on in my new employment was setup some form of System Management as we have several Linux hosts. However truth be told I have never had a System Management system for Linux hosts (due to a lack of time to implement one) and due to a number of tight deadlines I’ve had to put this on the back burner and spin up servers for additional roles.

This road however will lead to ruin so I have put a stop to the random spinning up of hosts for anything other than testing until I get something in place to mange all the configurations centrally. The question for me was what to use, I’ve heard of both Puppet and Chef, but I have no experience of them. So after doing a bit of reading I figured I’d go with Puppet as it seems to have most of the bases I am interested in covered.

Infiniband cluster Part 1

Overview and installing the operating system

Intro:

To facilitate testing of our software and so that support can model possible customer environments I was tasked with setting up a cluster with infiniband. I was excited as the system was a Dell PowerEdge blade cluster (our 1st blade system) and we have never used or deployed infiniband (this would be our 1st infiniband system), in fact other than a basic “we have heard of this and know (very) roughly what it is” no-one in the group had any real knowledge of it. After a few hours of searching the deepest recesses of the Internet I had a limited understanding of how to setup the system. I know how irritating it is to have to read the crud in order to find that wee gem of info so from here on I’ll mark the paragraphs of the article so those of you wanting to “just get it done” can skip them.
